An Improved Direct Measurement of Leptonic Coupling Asymmetries with Polarized $Z^0$'s

The SLD Collaboration, K. Abe

We report new direct measurements of the $Z^0$-lepton coupling asymmetry parameters $A_e$, $A_{\mu }$ and $A_{\tau }$, with polarized $Z^0$'s collected by the SLD detector at the SLAC Linear…
